Contexo.Info
A website about the foundations of molecular genetics and biology. An excellent site for those who are
looking for more details on DNA.

Time to Most Recent Common Ancestry
Calculator by Bruce Walsh
The goal is to use genetic markers (here on the Y chromosome) to estimate the TMRCA, the Time to the
Most Recent Common Ancestor (MRCA), which is how many generations the two Y chromosomes are from a
common ancestor. This site explains the various models used to determine TMRCA.

The National Human Genome Research Institute
The National Human Genome Research Institute (NHGRI) created the Talking Glossary of Genetic Terms to
help people without scientific backgrounds understand the terms and concepts used in genetic research.

Human Genome Project Information
The Human Genome Project (HGP) is an international effort to discover all the approximately 30,000 to
35,000 human genes (the human genome), make them accessible for further biological study, and determine
the complete sequence of the 3 billion DNA subunits (bases).

Short Tandem Repeat DNA Internet
DataBase
While the use of STRs for genetic mapping and identity testing has become widespread among DNA typing
laboratories, there is no single place where information may be found regarding STR systems. This web
site is an attempt to bring together the abundant literature on the subject in a cohesive fashion to
make future work in this field easier. Facts and sequence information on each STR system, population
data, commonly used multiplex STR systems, PCR primers and conditions, and a review of various
technologies for analysis of STR alleles have been included in this database.

GENEALOGY-DNA-L
This mailing list is for anyone with DNA (i.e., anyone!) who would like to discuss methods and share
results of DNA testing as applied to genealogical research.
